2 Chronicles 34:3-4

3When Josiah had been king for eight years, he was still a young man. At that time he began to worship God, as his ancestor David had done. When he had been king for 12 years, he started to remove the places in Jerusalem and in all Judah where people worshipped false gods. He removed the altars on the hills, the Asherah poles, the idols and the images of false gods.

4He told his men to knock down the altars where people worshipped the idols of Baal. He broke into pieces the altars for incense that were near the other altars. He destroyed the Asherah poles, the idols and the images. He broke them all into very small pieces. He threw the bits over the graves of the people who had offered sacrifices to those false gods.
